FILLED-BAG-SEWING APPARATUS.

Specification of Letters Patent.

Patented May 6, 1919.

To alLevhom it may concern:

Be it known that I, DUDLEY S. SEYMOUR,-

a citizen of the United States, residing at Oak Park, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in Filled-Bag-Sewing Apparatus, of which the following is a description, reference being had to the accompanying drawing, and to the letters and figures of reference marked thereon.

My invention relates to an improvement in filled bag feeding and sewing apparatus, as ordinarily constructed as shown for example in my application for patent filed January 6th, 1910, Serial No. 536,765; and in the patents granted John Bigelow, and C. H. Foster, December 31st, 1907, nu'm bered respectively 875,814 and 875,339, these apparatus including a supporting framework, an overhanging frame supporting a sewing head and a vertically adjustable conveyer table, over which runs a belt to deliver the bags to the sewing mechanism. If desired too, the sewing head may be made adjustable vertically. In an apparatus of this character, the conveyer is on the sup: porting framework, and the filled bags to be sewed must be placed by an operator on said conveyer.

In some factories where large sacks or bags are to be filled and sewed, an inde pendent conveyer of considerable length is sometimes used, which passes in front-of the packing apparatus, and when filled is placed upon this conveyer and carried toward the bag sewing apparatus. In such an arrangement, itis difiicult to cause the bags to pass from the one conveyer to the conveyer which forms a part of the bag sewing apparatus; hence an operative must stand beside the sewing machine to help the bags from one conveyer to the other.

It is the object of the present invention to adapt the sewing apparatus for use in connection with a conveyer which is inde-' pendent thereof, and which may be of any suitable length and adapted to convey the largest sizes of filled sacks to the sewing apparatus, without necessitating their handling from the time they are packed until they are sewed.

In an apparatus ofthis character, the

top of the conveyer is usually in a plane 00-.

incident with the plane of the floor. It is desirable to provide means whereby the con veyer can be operated without the necessity of operating the sewing machine, for the reason that when large bags are sewed if there were considerable space between two consecutive bags, the consumption of thread ifnlchaining between them would be wasteu in When the sewing machine however, is operating upon a bag fed along by the conveyer, the top of the sack must be fed along at the same rate of speed by the feed of the machine, as the body of the bag is fed along by the conveyer.

My invention therefore, comprises a con veyer and means for operating it, and a sewing mechanism carried on a framework overhanging the conveyer, with means for operating them in unison or one of them independently of the other, said means for operating them including a common motor, or independent motors, with clutches controlling the transmission of the power be tween them, the motor or motorsy and the conveyer and sewing mechanism, there being provided two treadles or other means of control, which may be operated either to simultaneously throw the devices into operation, or to operate one device independently of the other.

Further the invention consists in the matters hereinafter described and referred to in the appended claims. I The invention is illustrated in the accompanying drawings in which;

Figure 1 is a side elevation of an appara tus constructed in accordance with my invention;

Fig. 2 is aplan view; and

Fig. 3 an end elevation.

In these drawings;

The large conveyer is shown at 1. It may be of considerable length, forty feet more or less, and is arranged adjacent the packing stand, so that the bags when filled may be placed therein and carried to the stitching mechanism. Such a conveyer when used for large sacks, is preferably arranged so that its upper travel is at the floor line, so that the bags will not have to be lifted.

It is trained over rollers 2, journaled in bearing standards 3. It is operated by an electric motor 4, the shaft of which 5 has a clutch connectionb, with the shaft 7, carrying near its opposite end, the WOIfIYF" gear 8, moshing with the worm wheel 9, on

Inc

the shaft 10, which shaft also carries one of the rollers 2.

The clutch 6 is controlled by the treadle 11, which is attached to the long lever 12, pivoted at its opposite end to one arm of a bell crank lever 13, pivoted to a bracket 14 on the frame of the apparatus, the other arm 5 of the bell crank, engaging the clutch in the usual manner.

The movement of the conveyor is thus controlled by the treadle 11. The sewing apparatus and its supporting framework need not be specifically described, since they are the same as illustrated in my application for Letters Patent, filed January 6th, 1910, Serial No. 536,765. The sewing head is adjustable for the accommodation of the different sizes of sacks, and to regulate if desired, the position of the line of stitching in the bag mouth.

The sewing mechanism is operated from an electric motor 16, through the connections shown, a clutch 17 controlling the operation of said connections. The pivoted lever 18 operating the clutch, is attached to the connecting rod 19, and at its lower end is attached to an arm 20 on the horizontal rod 21, extending to the front of the machine, and connected at its outer end to the arm 23 supporting the treadle 22. The treadle 22 controls the operation of the sewing mechanism. It will thus be seen that the conveying mechanism may be operated 7 independently of the sewing mechanism, and

the latter may remain stationary, which is an advantage in the saving of thread in avoiding long chains between sacks it they are considerably spaced apart on the conveyer.

While it is desirable that the conveyor should operate at times without the sewing mechanism operating, it is also desirable that when the sewing mechanism is thrown into action, the conveyor belt should practically be started automatically as the feed of the sewing machine itself obviously can not feed the sack. Therefore, as a further and special improvement in. apparatus of this character, I have arranged the lever 23 of the sewing mechanism treadle, to cross over the lever 12 of the conveyor mechanism treadle, whereby when the treadle 22 is depressed its downward movement will depress the treadle 12, thus starting the conveyer or maintaining it in operation, if it has previously been in operation by depression of the treadle 12.

The clutch for the sewing mechanism and also the clutch for controlling the conveyor belt are each of the usual construction wherein a spring normally holds-the clutch members separated. The operator upon depressing the tr'eadlc overcomes the action of the clutch members. When, however, the treadles are released the springs will at once separate the clutch members and raise the treadles.

Any other means for the successive operation of the two treadles may be substituted, such as other connections between the treadle levers, or the operatives toot may bridge both treadles. In this way, the sewing machine and conveyor may be operated. together, or the conveyor independently of the sewing machine by moving the toe of the foot from one .treadle to the other, the Weight of the body resting upon the other foot and the heel.

As above stated, the feed of the sewing machine should move the bag mouth at the same speed as the conveyor belt moves the sack body. I
